Today I became a member and inadvertently, not being so computer savvy, posted my question about scalding hot water in cold tap in the "Forum Area." Anyway someone can help move this so I can get our question out thee without retyping? Thanks for your timel.
Ok you are in the right location now. Tell us more, does the hot tap also give hot water? Is this a single handled mixing valve, what brand?
Thank you for moving our inquiry. Sorry it has taken so long for our reply. I appreciate your kindness in trying to help. Our family has had to be away for some time now.
Yes there is hot water in the hot water taps and the faucet brand in kitchen is Peerless.
I think I stated in my question that the scalding water (in the winter only, and only when the furnace is used) comes after a few seconds of running a cold tap and is throughout home, including the toilet tank/bowl, shower, bathroom and kitchen sink. I also think I mentioned that a plumber told me it had to be a valve at the furnace. The mixing valve? The furnace heats our hot water.
Come September this year it will be interesting to see what happens as the landlord is converting heating systems. Our rental now has oil heat paid for by landlord. Beginning September we begin paying for heat (as so many landlords are doing today with the oil crunch); converting to natural gas/boiler.
The landlord's plumber has consistently told him at our three complaints we made in past that the reason is because the hot and cold pipes run side-by-side. Of course, this is ridiculous or we'd all be making a fortune having found a new way to heat water to scalding temperatures!
Our hope is this coming heating season this will be resolved. If not, we will have to take further steps to resolve the issue.
However, we are still insterested in what you may have to offer for answers or ideas. Thank you for taking the time to answer our question.
Hot and cold pipes running side by side or touching could explain your situation if it happened year round. Cold water pipes sitting on top of air ducts or other hot parts of your heating system seems to fit your situation. This may not change when the new system is installed.
Sounds like you have a boiler heating system that also provides domestic hot water. A defective mixing valve would cause the symptoms you describe. Conversion to a new system should resolve this.
Thank you. I agree with your answer as I have discussed the matter with two master plumbers and they said the same thing.:) :)Quote:

The one other apt. downstairs does not have heat provided as it has a wall system, and that apt. also gets scalding water from the cold outlets only when I use my heating that is provided from the landlord's furnace. Thanks again. I'll rate.
Sorry if I rated your answer, I am unfamiliar with this site. But, thanks for your thoughts!Quote:

I don't think so Bob. Heat conducts to cold, Not the other way around. I believe it's called "the Second Law of Thermodynamics" Regards, TomQuote:
